Too much cancer?

its appears that the rear window channel is probably gone also but really you would be taking that car all the way down to an empty shell then cutting and welding in panels. Im sure all the panels are available but still its alot of work its all in how much ambition you have and how much it will cost etc. You will most likely need trunk floors possible frame rails etc. there is possibly rot underneath. Even a rust fee appearing car may need trunk extensions etc.
